3 volt XHP50.2

That’s what I was imagining. But I’m confused because then how does the Q8 handle it? Is the driver more beefy in some way?

Yes, and you’ve got 4x 18650s, beefier power traces, much higher thermal mass and thermal dissipation potential.

Makes sense, thanks!

Here’s a similar build (1x18650 on a 4x4 die LED) mine lived but it pulls almost 30A from the battery:

Dale, any thoughts about trying one of these in an EE X6? Do you think the heat would be too much?

Just finished a X9 mod. I posted this is the X9 thread, but repeated here:

It's all done. Can "only" hit about 32 amps off a GOLISI cell. Recorded startup lumens at 10880 (TomE #'s). A black LK cell did 24.6 amps for 8640 lumens @start.

Used this for the reflows, driver and LED's:

Here they are reflowed on the X9 MCPCB:

Driver sandwhich, 20 mm FET+1 by DEL,trimmed slightly:

Checking fit, looks good:

MCPCB isn't perfectly flat but it's close. From flat surface sanding, you can tell pretty good:

Since up'ed the wires from 20 to 18 AWG, added kapton tape just in case:

Here she is, all lit up:

I wired both colored LED's in parallel. USB charging is lost. RED and BLUE - it's a little strange look'n.

Size perspective with other high output flooders, though the others are 3500K and 4000K with high CRI:

I'll have to try a Samsung 25S 18650 - might do little better.

This was an easy mod for the LED's, since this light came with SST-40's and a stock high performance FET based driver. The pill area though is pretty tight, so I used a good epoxy glue to mount the 20 mm driver on to the stripped stock driver to keep everything low - worked out well. Was hoping for 40+ amps but there's probably just too much restrictions - single 18 AWG wires, had to use 22 AWG spring bypasses because the springs are low profile and batteries fit tight, etc. The MCPCB is fairly thin, think 1.5 mm, but still way too thin for these.


Installed KD 6000k 3v in my XinTD C8 with mtn 17dd driver. Pulls 8.5 amps at tail with Sanyo GA battery. Slightly blue on low, more white on high. Nice beam and hot spot. Love it! Driver spring is Beryllium Copper. Tail cap is bypassed.

should probably check your springs. if they aren’t bypassed you will likely need to change them or add a wire bypass otherwise they will probably heat up and turn to mush after a few turbo sessions.

I was thinking about doing one in an X6, haven’t pulled the plug on it yet and will probably wait for a 12A LD4A to be honest. I think a direct FET+1 in the X6 may well be excessive, not that I haven’t done excessive in the X6 before…

I have 16 XP class emitters + one SST-40 in my Ham’r, a single 18650 Samsung 25S will deliver the second highest amperage I tested at 28A, second only to the 30.3A of a 30T. The Golisi pulled 27A. The single cells still gave pretty exceptional output, with the 25S putting out a little over 14,000 lumens and the 30T making just over 16,000.

That said, 4P 25S cells yield 26,200+ lumens.

(I should point out that I have a mix of Samsung LH351D emitters as well as Cree XP-L HI and HD emitters, with 5 separate FET+1 drivers powering each bank of 4 + the one SST-40. So each MOSFET only powers 4 Samsungs or 4 Cree’s and then the Master powers the SST-40 by itself. This is quite a different set-up from having one FET control all 16+1 emitters)

May swap one in my X6. Not sure what driver to use. Trying to keep the heat down. 8 amps is enough for me.

You picture a Supfire M6 in your post... I ordered three of these xhp50s for my M6. Can't get too warm, can it?

I can see everyone is putting these to flashlights where they want to squeeze them for even more power… Seems almost silly, that I put it in Wuben LT35 zoomie :smiley: It works really nice and as it has no reflector, no olive-green spill.

The Supfire M6 is going to get hot pretty fast. Mine has sense resistors bypassed. Has XML2 nw leds. Gets 3.25 amps to each led. Must be close to 3000 lumens. Gets hot after about 2 min. Stepping down to medium is plenty bright. I really like this light. I would not bypass sense resistors with 3v XHP50.2 without testing amp draw with new leds first.

Thanks contactcr for comment. Retested XinTD C8 tailcap amps this time with a clamp meter. Much better results. 10.2 amps. I’m going to have to stop using my cheap meter!

I’m planning on putting one in my H03 with a TA driver. I wonder what it’ll do haha

It will make you a hot head... hehe

Lol you’re not wrong! I figure if the wizard pro can do it, the H03 can too.
Surely it won’t be able to do max for very long at all, but I don’t need that kind of power all the time, just occasionally lol

Wizard pro probably isn’t using FET+PWM though which will be hotter (probably) at medium levels too

I modded a couple headlamps, but you usually got some padding there with the strap. I've gotten them pretty hot before realizing...

shrug I’ll report back lol

Edit: that is good to know though, thanks
